There have been big fires at this refinery before. You can't help but wonder about terrorism when something like this happens - and around here, that doesn't necessarily mean jihadis. We've got some pretty nasty Deep Green covens around here, too. As well as Occupiers and other such riff-raff.

There may well be a ripple effect that causes prices to rise elsewhere.

Part of the problem is that government regulations make it nearly impossible to build new refineries, and demand is high enough to make the short-term payoff of needed maintenance--necessitating plant shut-down--seem not worth it. So we hear more and more about issues with refineries that are wearing out with no replacements or relief in sight...
